I got same error today twice as I was trying to connect to Remote Desktop where strategy was running.

Note - just noticed - I also had FX Board window open, and when re-connecting with RDP - that window became blank (no tickers were showing there)...

Was using NinjaTrader Beta 9.

Added attachment to show the full message (forum doesn't accept more than 10000 characters in one post).

Here is a stack error:
